Introduction
Beris are 5-9 mm long and most species have a metallic green to blue thorax. The genus is Holarctic in distribution, with some species in Southeast Asia. Adults of Beris in North America have been collected near streams and lakes, resting on vegetation (Woodley 1995). Larval Beris are found in moist leaf litter and decaying vegetation. The larvae of Beris clavipes and B. vallata live in moss (Rozkošný 1998). The habits of adults and larvae of European Beris species are summarized in Rozkošný (1982).
Characteristics
Beris is distinguished from all other genera in the subfamily by the reduced, one-segmented palpus (Woodley 1995).
